Leaves opposite or verticillate, pinnate, with many entire leaflets: flowers medium-sized, yellow, white or rose-color in lax or dense cymes or fascicles; corolla funnelform, somewhat bilabiate, with 5 rounded spreading lobes; perfect stamens 4, didynamous. - Probably 15 species, but little known in cultivation They thrive in a fibrous earth and prop, by means of mature shoots in sand over bottom-heat.

Colic-Root

: Aletris farinosa.

Collabium

(neck and lip, referring to a peculiarity of the flower). Orchidacese. Two terrestrial orchids, of Java and Borneo, rarely cultivated, requiring the treatment given Catasetum. leaf single, plicate: flowers or clusters racemose, on a tall scape; lateral petals attached to the foot or base of the incurved column; lip at its base encircling the column (whence the generic name); pollinia 2. C. nebulosum, Blume. stems fleshy, about 2 in. long: leaf broadly ovate, acuminate, the petiole rounded: scape about 2 ft., erect; flowers numerous in scattered clusters or whorls, spurred, about 1/2in. long, the Up 3-lobed, white and a little fringed, the sepals and petals greenish with reddish margins.

Juice milky: flowers monoecious, apetalous; calyx imbricate or none in staminate flowers; stamens 1-5; ovary 2-4-celled, cells 1-ovuled. The following may be expected in botanical collections, although probably not in the trade: C. odorifera, Molina. Leaves serrate, ovate to oblong. C. brasiliensis, Klotzsch.
